Usual Top of My Location Page (#1*)	A “Go To” Waypoint or Route is Set (#2*)
At very slow speeds
At faster speeds

* When a “Go To” waypoint or a route is active, tap twice in the gray bar to switch between
(#1) and (#2).

Change the units displayed (e.g. degrees, UTM) by using the Settings App.

When using a “Go To” waypoint or a route with waypoints, the Distance and Bearing are for the straight-line to the next waypoint. The ETA and VMG are to the next waypoint.

When using a route converted from a track log, the Distance is along the curved route to the end of the route. The Bearing is the direction to the next point on the route. The VMG is to the next point on the route. The ETA is to the end of the route.

When a Location Accuracy background turns yellow, this indicates that the GPS satellite signals are not being received properly. Therefore your position may be off.

Removing Chart Margins

The option to remove chart margins is selected using the Settings App.

Remove Chart Margins OFF	Remove Chart Margins ON
Chart margins are shown.	Chart margins are hidden.
Zoom out to show the entire length of very long tracks and routes.	Zoom out is limited to less than the size of the currently visible chart.

In the Chart Area

The direction of the Course Indicator shows Course Over Ground (COG). The length of the Course Indicator is proportional to Speed Over Ground (SOG). At speeds less than 4 knots, the Course Indicator is not shown because GPS Course measurements are not accurate at these slower speeds.

Chart List Page:

TAP	TO DOWNLOAD A CHART
Current Location	For where you are.
Relative to Current Chart	North, South, East, or West of the chart currently showing on the “My Location” page.
Same Chart Location	A chart with a different scale for the same area.
Coastline Locator *	Find the place you want on a coastline map.
Place Name or Chart Name	Search for Latitude and Longitude by:     Chart name     NOAA chart number *     City     Geographic feature Add a comma, a space, and the 2 letter state abbreviation.
Latitude & Longitude	In the USA, use a minus sign in front of longitude numbers.

* Use WiFi or cell service.

There are usually several charts for a given location, each with a different scale. Once you obtain the latitude and longitude by using one of the options above, the scale bar shows the available chart scales for that location.

Tap the button for the scale you want, then tap Add NOAA Chart.

* The Coastline Locator also shows the border lines of your downloaded charts:

To Download Charts with Multiple Sections:

* Each chart has a number, such as 25668, assigned by NOAA to the chart.

Many paper charts have multiple charts printed on one piece of paper. For example there may be one chart section showing an entire bay, and a second chart section showing a close-up of a harbor. These individual chart sections are indicated by an underline character and a section number added to the end of the chart number.

The main chart section is indicated by _1, for example 25668_1. The close-up sections are indicated by _2, _3, etc.

On paper, the close-up chart sections are often shown as insets. In iSailGPS, each chart section is shown individually so that each can have its location properly referenced.

To download all sections of a multi-section chart:

1. Tap the “Chart List” tab.
2. Tap the + button.
3. Tap “Place Name or Chart Name”.
4. Enter only the main chart number under “Search for the Coordinates for”. For example enter 25668, not 25668_1.
5. Tap the “Search” key on the keyboard.
6. In addition to returning location coordinates, under “Search for the Coordinates for” iSailGPS will return the full chart number for the last available chart section. For example enter 25668, tap “Search”, and you will see 25668_3. That means that chart 25668 has three chart sections.
7. To download all three sections, individually download charts 25668_3, 25668_2 and 25668_1. Enter each full chart section number under “Search for the Coordinates for”. Tap “Search” on the keyboard. Then tap the “Add NOAA chart” button. Repeat for each chart section.

Up to 500 charts can be stored at one time.

• Tap “Bluetooth”, then turn Bluetooth off.
• Tap “Brightness & Wallpaper”, then turn down the screen brightness to the lowest acceptable level.
• Tap “iCloud”, then tap “Documents & Data”, turn off “Use Cellular”.
• Tap “Mail, Contacts, Calendars”. Tap “Fetch New Data”. Turn off “Push” and tap “Manually”.
• Tap “iTunes & App Store”, then turn off “Use Cellular Data”.

Also:

• Plug the iOS device into a charger before your trip so that you start with a completely charged battery.
